1. Each song has a different time signature, but the more commonly used ones are 2/4 and 4/4. There are also 3/4, but relatively less. The tunes in 2 beats are mostly cheerful and clear; the songs in 4 beats are mostly lyrical and slower. ?

The drum beats of 2 and 2 generally have a relatively obvious drum beat, with the first sound being strong and the second sound being weak. The four notes of the 4 beat are strong, weak, sub-strong, and weak. 3 beats are even simpler: strong, weak, weak. You can tell the difference by listening more.

Example:

(When listening below, pay attention to the words marked in black, and then listen carefully to the strength of each instrument (in layman terms, it is the volume size), especially percussion instruments)

First of all, take our national anthem March of the Volunteers as an example, a 2/4 time march in G major, and most people are familiar with it:

Get up ! People who don’t want to be slaves! Build our new Great Wall with our flesh and blood!...

Military Song March of the Chinese People’s Liberation Army:

Our team faces the sun...

Consolidation: Welcome March Farewell March Athletes March Song Singing the Motherland Cancan Dance Double Eagle March

When you really hear the changes in the music, no written explanation can compare to the music you have established. The sense must be strong.

Extended information:

Music always alternates between strong beats and weak beats. This alternation cannot be chaotic or arranged arbitrarily, but forms the smallest rhythm organization according to certain rules. a section, and then repeat from there. For example, when there is only one weak beat between two strong beats, it is called "two beats", which is the type of 2/4 beat; when there are two weak beats between two strong beats, it is called "triple beat", Like 3/4 and 3/8; there are three weak beats between the two strong beats, which are called "four beats", and the most common one is 4/4.

Two sections are separated by a "section line". The bar line is a thin line perpendicular to the staff, with five lines on top and one line on the bottom, which just cuts off the staff. No matter how far away the upper and lower lines are from the staff, the bar line cannot go beyond the staff. Draw two bar lines in the last section of the work, and the one on the right is thicker, indicating the end of a work or a paragraph. The beat after the bar line must be a strong beat. There is only one strong beat in each bar, and the rest are weak beats.
